With just 6,500 residents, the Town of Eagle is known for its mountain biking and beautiful trails. Located 30 minutes from Vail, it is a haven for people who love the outdoor lifestyle,providing endless hiking and biking during the summer and easy access to world-class slopes in the winter.
In 2018, at 90% of its peak capacity, the struggling water treatment plant needed a significant upgrade to meet the demand of a growing population. The Town of Eagle moved forward with plans to construct a second water treatment facility. Using water from the Upper Brush Creek, the Lower Basin Water Treatment Plant added an additional 2.5 million gallons a day (MGD) to the Eagle community, with the ability to expand to 5 MGD if needed. The new plant is projected to provide quality water treatment to the area for the next 20 years.
Winter conditions in the high country can extend into spring, which required MWH to plan carefully in order to keep the project on schedule despite unpredictable weather. This project utilized a Suez Water Membrane Treatment System. Other scopes of work included flocculation and sedimentation basins, chlorine contact and clear well basins, a hydrostatic membrane tank, and raw water pump station. The project also encompassed electrical work, yard piping, reinforced concrete, HVAC, as well as startup and commissioning. MWH self-performed work, including, process piping, process equipment, and demolition.
The Lower Basin Water Treatment plant will not only ensure water requirements are met, but it will also provide greater reliability, flexibility, and redundancy in the system itself. By having a second filtration plant, residents are ensured a continuous supply of water in the event of contamination (wildfires being a primary concern).
"MWH proved itself to be a knowledgeable and thorough water/wastewater contractor. The field team showed great attention to detail and an ability to quickly address any needs for the project. The self-perform crew was a great addition to the project and allowed for a quality process mechanical installation. We also found MWH’s commitment to safety and quality to be meaningful, with proactive approaches and regular monitoring that resulted in an excellent safety and quality record throughout the project."
The Bull Run Filtration Facility in Gresham, Oregon has earned the Envision Platinum Award, the highest honor from the Institute for Sustainable Infrastructure, recognizing its exceptional commitment to sustainability, environmental protection, and long‑term community benefit. As a major investment in the region’s drinking water system, the project will improve water quality, enhance reliability, and protect the Bull Run Watershed for future generations. The award highlights strong collaboration among the Portland Water Bureau, design teams, construction partners—including the MWH‑Kiewit joint venture—and community stakeholders, as well as leadership in climate resilience, resource efficiency, and workforce equity.
